No, it does not. If you had read at least the abstract of the paper instead of jumping to conclusions, you would have noticed, that they examined the role of galatic cosmic rays. As the name says, those are coming from the galaxy, not the sun. Solar activity is unrelated to the presence of galactic cosmic rays, so your statement is wrong. And if "skeptics" cannot be bothered to do basic fact checking, they should not be wondering why scientists tend to be hostile. And how do you know the scientific background of the people posting here?
